Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle engineering, and specifically relates to an independent link type balance structure. Background Art

[0002] The suspension system is the general term for all force transmission connecting devices between the vehicle frame and the axle or wheels of an automobile. Its function is to transmit the forces and torques acting between the wheels and the vehicle frame, and to buffer the impact force transmitted from the uneven road surface to the vehicle frame or body, and to attenuate the vibration caused thereby, so as to ensure the smooth driving of the automobile.

[0003] The trailing arm independent suspension system is a suspension system structure in which the wheels swing in the longitudinal plane of the automobile, and is divided into two forms: single trailing arm type and double trailing arm type. When the wheels move up and down, the caster angle will change greatly in the single trailing arm type suspension system. Therefore, the single trailing arm type suspension system is not used on the steering wheels. The two swing arms of the double trailing arm type suspension system are generally made of equal length to form a parallelogram four-bar structure. In this way, when the wheels move up and down, the caster angle of the kingpin remains unchanged. The double trailing arm type suspension system is mostly used on the steering wheels. In the prior art, the link type trailing arm suspension is generally a multi-link structure, and its bilateral wheel synchronism is poor. When the turning angle is too large, the damping effect is significantly reduced, especially when the loads on the left and right sides of the vehicle are unbalanced. In this case, how to improve the balance structure of the link type trailing arm suspension has always been a technical problem to be solved. Summary of the Invention

[0004] The technical problem to be solved by the utility model is: how to improve the balance structure of the link type trailing arm suspension.

[0005] To achieve the above technical purposes, the utility model adopts the following technical solutions:

[0006] An independent link type balance structure includes a cross beam, a bridge frame, a reinforcing plate, a support rod, a swing arm, a bushing, a mounting seat, a mounting hole, a connecting rod, a pin head, a support column, a brake disc, a shock absorber, a collar, and a wheel. Among them, the cross beam and the bridge frame are arranged in parallel. A reinforcing plate is connected between the cross beam and the bridge frame. There are two upper and lower support rods arranged outside the reinforcing plate. Swing arms are rotatably connected to both the upper and lower support rods. A bushing is provided at the inner end of the swing arm, and the bushing is rotatably connected to the support rod. Mounting seats are provided on the opposite sides of the two swing arms. The shock absorber is located between the two swing arms. Collars are provided at both ends of the shock absorber, and the collars are rotatably connected to the mounting seats. A mounting hole is provided at the outer end of the swing arm. Pin heads are provided at both ends of the connecting rod, and the pin heads are rotatably connected to the mounting holes. The support column is connected to the connecting rod. The wheel and the brake disc are mounted on the support column.

[0007] Preferably, at least two cross beams are provided, and a reinforcing rod is connected between adjacent cross beams. The extending direction of the reinforcing rod is parallel to that of the reinforcing plate.

[0008] Preferably, through holes are provided in the reinforcing plates, and the through holes in the two reinforcing plates communicate with each other and are perpendicular to the plane where the reinforcing plates are located.

[0009] Preferably, a limiting spring is connected between the reinforcing plate and the swing arm, and the limiting spring is a conical spring.

[0010] Preferably, a fixing plate is provided at the end of the support column, the support column penetrates into the tube body in the middle of the connecting rod, and the fixing plate is fixedly connected to the tube body.

[0012] Preferably, a plurality of rib plates are provided between the reinforcing plate and the bridge, and the plurality of rib plates are parallel to each other.

[0013] In the above technical solution, the cross beam plays a main supporting role; the bridge is arranged in parallel with the cross beam. On the one hand, it strengthens the structure of the cross beam, and on the other hand, it shares the force to ensure the stability of the overall structure; the reinforcing plate plays a connecting role at the ends of the cross beam and the bridge, and on the other hand, it is used to set the support rod; the support rod is connected to the bushing, so that the swing arm can be rotatably connected to the support rod. The upper and lower swing arms can rotate along the horizontal axis, thus constructing a movable connection structure of the wheel relative to the cross beam. Based on this movable connection mechanism, a shock absorber is set, which can play a role in buffering and shock absorption; the mounting seat on the swing arm is used to connect with the ring sleeve of the shock absorber, so that the shock absorber can be connected between the two swing arms. Therefore, when a bumpy movement occurs, the shock absorber can play a buffering role and at the same time limit the distance between the two swing arms; the mounting hole at the end of the swing arm is used to connect with the pin head at the end of the connecting rod, so that the connecting rod can be rotatably connected to the sides of the two swing arms. Since the wheel and the brake disc are installed at the end of the connecting rod through the support column, the steering movement of the wheel can be realized.

[0014] The present invention provides an independent connecting rod type balance structure. This technical solution constructs a support structure based on the cross beam and the bridge, and relies on this support structure to set double-layer swing arms that move synchronously. The shock absorber located between the double-layer swing arms plays a role in buffering and shock absorption, and the special-shaped connecting rod at the end is used to realize the steering movement of the wheel. The present invention can maintain good shock absorption during large-angle turning, and is less affected by the phenomenon of uneven load on both sides, having significant technical advantages.
